Positive test fading. Chemical question

Kachelle

Hi everyone I mc in dec at 6 weeks. I ovulated and tried again jan cycle.

Tested 11-112dpo and got faint positives but they never progressed darker and so I took one today this AM they got lighter. (Period due today) zero pregnancy symptoms.

I know in having a chemical.

What happens next? Do I bleed when period is late how late?

Do I bleed once my test are back to neg?

Does this count as “a period” moving forward to track my next cycle?

Thanks for any info
